Hi all!
I wrote days ago: I have a problem with virutal interface and iptables:
my pc has 2 network interface, one with a private network address and the
other one with public network addresses:
eth0 --> 192.168.1.254 / 255.255.255.0
eth1 --> 82.186.92.90 / 255.255.255.248
eth1:1 --> 82.186.92.91 / 255.255.255.248
eth1:2 --> 82.186.92.92 / 255.255.255.248
eth1:3 --> 82.186.92.93 / 255.255.255.248
eth1:4 --> 82.186.92.93 / 255.255.255.248
The problem is that I can't access to services running at virtual
interfaces. I tried to solve the problem as suggested me: I've seen that using alias is
deprecated so I tried using iproute: I set up with ip addr add 82.186.92.90/24 brd 82.186.92.95 dev eth1 label eth1:0
ip addr add 82.186.92.91/24 brd 82.186.92.95 dev eth1 label eth1:1
ip addr add 82.186.92.92/24 brd 82.186.92.95 dev eth1 label eth1:2
ip addr add 82.186.92.93/24 brd 82.186.92.95 dev eth1 label eth1:3
ip addr add 82.186.92.94/24 brd 82.186.92.95 dev eth1 label eth1:4
but after service iptables restart anything changes, alias's rules doesn't
be applied and no errors is reported. I think I'm doing something wrong with iproute but I don't know what: shoud
I give any command to enable iproute?
well, for starters, a /24 network of your ip addressing should have a broadcast address of 82.186.92.255 - if your broadcast ip you have there *is* your broadcast address (.95), your network is diced up a bit more.. if you know the size of your ip address space, this may help?
